Why

It took me several days to figure out how to set up a fully encrypted machine with 2FA. This guide should help
others to get it done in minutes (hopefully). There exists a plenty bunch of tutorials but no one contains a step-by-step
guide to get the above things done.

I guess the entire manual will take between 1 - 3 hours.

Prerequisites

You should be familiar with linux and should be able to edit files with viVi Cheat Sheet.
You need an USB stick for the Linux Live environment and a second computer would be useful for look ups and to read this guide while
preparing your fully encrypted Linux.
